It is worth specializing the Cwikel estimates of Section  to operators of the forms \(\lambda (x)\Delta ^{-n/2p}\)  and \(\Delta ^{-n/4p}\lambda (x)\Delta ^{-n/4p}\) , since these estimates are used in the derivation of the CLR inequalities on NC tori in Section . In the terminology of [1]} these Cwikel-type estimates are called specific Cwikel estimates.
